Study Finds: Long Sleep is Unhealthy
Everyone needs enough sleep to do their normal daily routine. If we sleep too little, it is not healthy for our body and we can suffer from negative complications. Thus, it is often advised that people have to pay attention to adequate sleep. However, you should not sleep more than eight hours a night, otherwise your risk of heart disease increases.
Are you one of those people who like to sleep as long as possible? If so, you should be careful, scientists from the Norwegian University of Science and Technology found in a study that their risk of developing heart disease increases when they sleep over eight hours a night. The Norwegian researchers published the results of their study in the journal "International Journal of Cardiology".
More than eight hours of sleep increase the risk of heart disease by almost 35 percent
If people sleep too little, it can have negative health consequences. But too much sleep can also be unhealthy, the experts say. The scientists found that sleeping more than eight hours a night increases our risk of developing heart disease. If people sleep more than eight hours a night, the risk of heart disease increases by up to 34 percent. If you sleep less than four hours a night, your risk of cardiovascular problems also increases by about 35 percent, the doctors explain. Previous studies had linked sleep deprivation to stress. A lack of sleep can also cause increased blood pressure. These factors increase the risk of heart disease.
However, researchers from the Norwegian University of Science and Technology are not sure why more sleep leads to a higher risk of heart problems. We do not know which mechanism has a direct causal relationship between long sleep and an increased risk of heart disease, says lead author Dr. Linn Beate Beach.
Women generally have a higher risk of complications
The study evaluated data from 400,000 Taiwanese adults. These were examined medically between 1994 and 2011. The participants were asked how long they sleep each night, the scientists say. The results showed that people who slept between six and eight hours a night were most likely to die later from cardiovascular problems.
In a follow-up study, the researchers found that 711 people had died of cardiovascular diseases. The study also showed that women are generally at higher risk of developing such complications, the researchers explain. Women are more susceptible to these problems than men. Earlier studies have shown that too little or too much sleep in women is associated with an increased risk of cardiovascular diseases, explains Dr. Beach. Our results show that enough sleep is needed, but too much sleep is unhealthy for people. the researchers continued. The study's authors emphasize that adequate sleep is an important part of a healthy lifestyle. (as)
